摘要：

Formation of ordered tetragonal PtCo from epitaxial Pt(001)/Co(001) multilayers was observed via in situ X-ray diffraction measurements at four different annealing temperatures. The measured activation energy of formation of ordered PtCo is 2.1+/-0.2 eV. Ordering in the PtCo phase is not complete even after 1100 min annealing at 570 degrees C. Growth proceeds by nucleation of domains less than 10 Angstrom in thickness, which thicken at a rate approximately proportional to the square root of time.
